Galenas was a tall plant of the nicotiana family, originally native to temperate scrublands and moors, later cultivated. When dried and slowly burned, galenas leaves produced an incense-like smoke which filled a twenty-foot radius volume, relaxing all persons within for several minutes.

Sweet galenas was a specific breed of galenas used primarily by Hobbits as pipeweed.A related but unenjoyable variant was Bitter Galenas.
